I have my 49 GMC 1/2 ton ready to put the wiring back in and I was wondering which method would be the easiest or best. The 49 has a V8 and a steering column from my 77 GMC truck in it. I was going to use a wiring harness from my 77 GMC truck and mod it to fit my 49. Or would it be easier to use the stock 49 harness and adapt them to the 12 volt system? Or should I buy a harness from Painless?
Thanks.

Buy a new 18 / 20 Cct. harness and save yourself a lot of grief. | | | | | Joined: Oct 2006 Posts: 4,983 Master Gabster | | Master Gabster Joined: Oct 2006 Posts: 4,983 | I would not trust 30+ year old wiring. You will be removing it from the donor and working it into the 49. Lots can happen that you wouldn't want to happen.

Any dealers up in Canada where I could get a 18 or 20 circuit harness? I know of The Old Car Center in Langley.

I'm using a painless harness I bought years ago from someone on this sight for a killer price. I was a bit hesitant to begin but it looks quite simple. All the wires are marked the full length of each wire taking out the guess work. I would definately recommend this kit.

With that said, get a new harness from whichever vendor you want, (I've had a personal issue with American Autowire and can't recomend them)and when you're done have peace of mind as you ride and guide your new truck, smiling with the knowledge that this is one thing you won't be working on from the shoulder of the road with a flashlight in the rain. | | | | | Joined: Oct 2006 Posts: 4,983 Master Gabster | | Master Gabster Joined: Oct 2006 Posts: 4,983 | Just ordered my harness from American Autowire. ... should be here this week sometime. The painless seemed to be easier to install but I decided on the American A. because I will be able to mount my fuse box anywhere I want or need to.
